there, james lee had a history with discovery channel. he was arrested in 2008, charged with disorderly conduct and ordered to stay 500 feet away from that building. when you got this call then, did you have a good idea of the man you would be dealing with? >> well, we very quickly got that information from the security folks at discovery. discovery was aware of the threats that -- history with this man. the security guards working at discovery, i think still had the information, including a picture of mr. lee at their disposal. we were very quickly aware of who we were dealing with. >> this is an incredibly scary situation, obviously. especially for the folks involved. two employees and a security guard held hostage. they were able to evacuate the building. even after the suspect was killed, as you are looking at two boxes, a couple of bags, thinking that there could be explosives, at what point did you know, though, that, in fact, everyone was safe?
